Product description: UHMWPE has perfect performance because of its high molecular weight, which is from 1.5 million to 12 million, and ordinary PE is only 20-30 thousand.Product performance: 1. High abrasion resistance UHMWPE ranks first for its abrasion resistance in plastic line, whose capacity exceeds some certain metals¡¯. Its abration resistance is in direct proportion to the molecular weight, that is molecular weight is higher, the abration resistance is stronger. 2. Superior impact resistance The impact strength of UHMWPE is at the top one among engineering plastics, is two times than that of PC, ABS five times, POM and PBTP more than 10 times. Its impact intensity will be increased when the molecular weight get more, however, when the molecular weight is up to 2.2 million, the impact intensity will reach to its maximum). 3. Self-lubrication UHMWPE has excellent self-lubrication because of its very small friction coefficient which is 0.05-0.11. Its lubrication is second only to the polytetrafluoroethylene (PTFE) in the circumstances with no lubricating conditions. When it works through sliding or rotating, its lubrication is better than steel and brass with lubricating oil. 4. Excellent chemicals resistance UHMW-PE has good resistance to chemicals, which can be against of corrosive mediums, such as acid, alkali, salt and most organic mediums, in the scope of certain temperature and concentration, but except fluoride acid liquor with high degree. 5. Absorption of impact energy UHMWPE has wonderful absorption of impact energy which is the highest among all plastics. Therefore, UHMW-PE has fine noise damping and reduction.) 6. Healthy and non-toxic UHMW-PE is health and non-toxic and is in line with the standards of Japan Health Association. UHMW-PE has got the approval of the Food and Drug administration and the Ministry of Agriculture of the United States, which can touch foods and medicines directly. 7. Non-sticky Performance UHMW-PE has low non-sticky adsorbility, which is behind to PTEE, which is famous for its non-sticky performance. Thus, the surface of products is hard to be sticky to other materials. 8. Hydrophobicity. UHMW-PE has a low rate of water absorption, which is generally speaking less than 0.01 percent, about 1 percent of PA6.Therefore, UHMW-PE needn¡¯t drying treatment before forming process.

ltra-high molecular weight polyethylene impact resistance and shock absorption can be among the top of the plastic, whether strong impact force, or internal pressure fluctuations are difficult to make its cracking.The impact strength is 10 times of nylon 66, 20 times of polyvinyl chloride (PVC), 4times of polyethylene.Especially in the low temperature environment, its impact strength achieve to higher values.The flexibility of Ultra-high molecular weight polyethylene provides the guarantee of safe and reliable toconveying system. 2. High wear resistance In many pipe material, the minimum friction coefficient of ultra-high molecular weight polyethylene and its has a long chain, make the wear resistance of UHMW-PE pipe during transportation of slurry is 4-7 times higher than steel pipe and stainless steel tube, about 10 times higher than PVC pipe and PE pipe, greatly improve the service life of the pipeline. 3. The corrosion resistance Based on UHMW-PE is a saturated molecular structure, so it has high chemical stability.In a certain temperature and the concentration range can resist all kinds of high corrosive medium (acid, alkali, salt )and organic solvents. 4. Do not knot dirt The self-lubrication ,adhesion,minimal friction coefficient of UHMW-PE.And pipe wall has corrosion resistance, wear resistance, not knot dirt by special process.So the flow resistance is small, can be keep flow velocity and flow rate for a long time.The diameter reduced by 15.4% than steel pipe. 5. Weather resistance and aging resistance The black modified UHMW-PE pipe has good weather resistance and aging resistance.On the one hand,the unsaturated chain of the molecular chain rarely and large molecular weight of the pipe;On the other hand, specially crafted improver making the UHMW-PE pipeline’s service life greatly more than the ordinary polyethylene pipes.Using about 60 years, UHMW-PE pipeline can remain more than 70% of the mechanical properties. 6. Wide optimum temperature Can be work from - 269 ℃ to 80 ℃ for a long time. 7. Fire resistance Used for fire protection in special industry, join the flame retardant and use special processing craft to overcome the flammability of UHMW-PE itself. 8. Light weight, easy to install This product has good toughness.It Can adapt to various geological conditions, can be directly bent laid.The flange connection, without spacer block, fast and easy to connect.

uhmwpe roller has the following superior features: 1. UHMWPE roller is made by UHMWPE whose abrasion resistance is 10 times than that of HDPE and 7 times than steel¡¯s. As its this special feature, UHMWPE roller can be widely used in application of mining industry, coastal industry and so on. 2. Absorption of impact energy UHMWPE has the highest impact strength among any other engineering plastics, about three times than that of nylon, two times than that of PC, five times that of ABS. UHMWPE roller can stand repeated impaction and has superior abrasion and corrosion resistance. UHMW-PE has made itself ideally to be suitable for industrial applications in complicate and rough environments. 3. Effective sealing system The primary labyrinth seal prevents most of the dust to get into the bearing house, and no water could leak in. The narrow clearance between bearing house and shaft forms the second sealing, the bearing house are made of UHMWPE which has a very low surface energy and are anti-adhesion, so it is repulsive to dust and water. It is quite difficulty for dust to get through the narrow channel 4. Light weight and energy saving UHMWPE rollers are only one third less in weight than steel roller, they are even lighter than HDPE roller, since they have superior strength .Light weight and low friction result in considerable energy saving. 5. Reduced belt damage UHMWPE roller is self-lubricant, and prevent the adhesion of any transfer material, so there is little damage resulted by conveying the belt, not mention to make the roller stop working. 6. Noise reduction UHMWPE is a good noise obstruction material . It generates much less noise than conventional steel roller and HDPE. Therefore, UHMWPE is very environmentally friendly. 7. Corrosion resistance UHMWPE roller can withstand humidity, corrosive chemicals, acids, salt and alkalis. 8. No sticking UHMWPE could not be sticked by any material, so no conveyor material will be sticked to the roller¡¯s surface.
